No, it is not necessary. Only if you want to get an IIT, NIT, IIIT, etc. you should write it.
These all are government aided colleges (central government).If you want to study in private universities like VIT, BITS Pilani, SRM then you have to write their entrance exams. They never see your JEE marks.
Then, if you want to get some good colleges where they accept JEE main scores and board exam scores, then to increase your chance of admission you may write it.
Otherwise, it is never compulsory to write JEE exam and you can get a good college for B.Tech through your board exam marks itself.
